TermDefinition
Aftershock An earthquake that occurs later along the same fault zone as a major earthquake, but before the area has returned to its normal level of seismic activity

epicenter Location on Earths surface directly above an earthquakes focus, or origin
P-wave A primary (compressional) earthquake wave that travels through the body of Earth; so named because it is the first wave to reach the seismograph station during an earthquake. See also P-wave
surface wave An earthquake wave that travels at or near the surface of Earth.
S-wave A secondary earthquake wave, so named because it travels slower than a primary wave and is the second wave to reach the seismograph station after an earthquake. It travels through the body of Earth as a series of crests and troughs. See also P-wave.
